Imagine if you will for a moment what are the properties that would constitute the ideal fertilizer and soil amendment for the most comprehensive spectrum of crop and soil applications. Fertilizers supply plant nutrients that assist in optimizing plant health, crop quality, and yield and are necessary for plant photosynthesis. Fertilizers are characterized by physical, chemical and biological properties. Plant fertilizers come in numerous forms, some are liquid, some are gaseous and others are solids. These fertilizers come in almost infinite nutrient ratios(N-P-K), and possess varying degrees of solubility or rate of release.

      Fertilizers can be derived from naturally occurring minerals and organic substances. They can be synthesized from atmospheric nitrogen, mined from geologic deposits and harvested or manipulated from materials of plant or animal origin. There are designer fertilizers that have been demonstrated to be optimum for nourishing certain plants or specific crops in wide ranging soil types and climates.

      They all have a cost / benefit ratio. Some fertilizers utilize significant energy to manufacture or deplete mineral reserves and fossil fuels. Other fertilizers may be “free” for the hauling but have a low nutrient density, or contain contaminants such as heavy metals. Some require more cost and energy to transport and apply than can be derived from the benefit of a crop, garden or lawn. Some fertilizers supply more than just NPK (nitrogen phosphorous, potassium) – the “primary nutrients”. Material scan change soil physical properties for better or for worse. Certain fertilizer scan have a negative impact on the environment in which they are used.

Compost is the one broad category of fertilizer sources that has repeatedly demonstrated a broad range of positive plant and soil amending characteristics. For example, here are compost product claims that are exempt from providing proof of claim or usefulness as required by the American Association of Plant Food Control Officials(AAPFCO) because these benefits have long been associated with quality compost materials:

• Compost improves soil structure and porosity – creating a better plant root environment;
• Increases moisture infiltration and permeability and reduces bulk density of heavy soils– improving moisture infiltration rates and reducing erosion and runoff.
• Improves the moisture holding capacity of light soils– reducing water loss and nutrient leaching, and improving moisture retention
• Improves the cation exchange capacity (CEC) of soils
• Supplies organic matter – and more specifically high quality humus
• Aids in the proliferation of soil microorganisms
• Supplies beneficial micro organisms to soils and growing media, as long as the supply is quantified and guaranteed
• Allows plants to more effectively utilize nutrients, while reducing nutrient loss by leaching
• Enables soils to retain nutrients longer
• Contains humus– assisting in soil aggregation and making nutrients more available for plant uptake
• Compost buffers soil pH.

What more could one ask for in complete fertilizer and soil amendment?

      Now imagine a compost that contains the highest concentration of primary, secondary and tertiary plant nutrients known to exist from any organic source. A compost product concentrated, granulated, predictable, guaranteed and demonstrated to help suppress a wide range of soil and plant pathogens. A compost that is so safe to use that it is the only organic fertilizer allowed for export worldwide. A fertilizer so efficient that it can provide equivalent growth to some other fertilizers – synthetic or organic, but with 1/3 to 1/2 of the amount of soluble NPK supplied. 

       Suståne Natural Fertilizer separates from all other organic fertilizers, compost based or otherwise. Suståne has the proof to back up any claim product benefit or feature that is made. Since 1980 the Suståne database surpasses the number of studies of other commercially available organic fertilizers. Suståne Natural Fertilizer, Inc. backs up a claim made.

       No one single fertilizer – Suståne included – exhibits optimal plant performance every time. Nature is not that simple. There are more variables in the plant world of cultivated agriculture and ornamental horticulture, than science may ever be able to examine. After 30 years of applied research Suståne has consistently proven to be close to the ideal fertilizer.

“When it comes to knowing soils
            all that matters is organic…”

      Suståne is serious about keeping the environment green. Aerobic, thermophilic composting is the most environmentally friendly practice for organics conversion and recycling. Aerobic composting generates less methane and other serious greenhouse gases than other organic stabilization strategies do. Utilizing renewable agricultural resources, composting and concentrating humus, Suståne creates a unique base of products with significant soil and plant fertility value that can be efficiently applied anywhere plants are grown for either commercial or aesthetic value.

Suståne is serious about making real compost.

Aerobic (oxygenated) compost is the base from which all Suståne fertilizers are made.

The Suståne composting process utilizes turkey litter – the highest in total plant nutrient density and carbon of any agricultural or industrial resource available.

 Suståne has been a national leader in recycling and composting since 1980.
